TELEPHONE ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 597,213, dated January 1 1, 1898.

Application filed November 16, 1896. Serial No. 612,209. (No model.)

T 0 all whom it may concern.-

Be it known that I, PHILIPP J OHANN BosE, a citizen of the free and Hanse town of Bremen, German Empire, have invented certain new and useful Improvements in Telephone Attachmen ts,of which the following is a specification.

My invention *elates to an improved device for holding a telephone receiver or receivers in convenient position relatively to the transmitter, so that the receiver maybe easily adj usted to the head for use and held for any required length of time without annoyance or requiring the employment of the hands of the person using the instrument. Unskilled persons may thus freely use the instrument and the hands are left free for holding papers or for writing down communications.

In apparatus as heretofore constructed it is intended that the receiver when not in use should be suspended upon a hook connected to the transmitter, so that the hook is pressed down by the receiver and makes contact with the call-bell. When the receiver is taken off the hook, the line-wire is brought into circuit. It is not infrequently the case that the receiver, after it has been. used, is not hung up in place, and-the apparatus is sometimes used by persons who are ignorant of the method of its use.

The object of my invention'is to provide an improved device for holding the receivers automatically and for relieving the person using the instrument of the above-named and other inconveniences.

In the accompanying drawings, Figure l is a front elevation of a telephone call-box with my improved device attached; Fig. 2, a side elevation of one of the bracket-sections,partly in section; Fig. 3, a sectional plan of one of said brackets; Fig. 4, an enlarged sectional elevation indet-ail of the upper end of the bracket-shaft; Fig. 5, an enlarged side elevation of the lower end 5 Fig. 6, a similar front elevation of the lower end of the bracketshaft, and Fig. 7 a sectional plan thereof in line a; w of Fig. 6.

To the right and left of the call-box A are fitted wall-plates B, one above the other, and

having eyes I), in which are .journaled the pivots c of the rods 0, the said pivots being surrounded by coiled springs (1, one end of which extends on one side against the plate 13 and the other end of which is secured in slits in the pivot c, as clearly shown in Figs. 2 and 4. The springs d are covered and protected by caps cl, which are screwed upon the threaded ends of the spindle c at each end of the said rods. The rods Gare prismatic and on them slide loosely the sockets F of the tubes G G G which telescope one within the'other. The outermost tube G is attached to the socket F. The others slide in the outer tube and form in effect a telescopically-sliding arm extending rectangularly from the rod C and having vertical adjustment thereon and adapted to remain in the position in which they are placed because of the cramping of the socket F upon the rod G due to the leverage and weight of the receivers (shown by dotted lines) suspended in the hooks Gr at'their ends. The springs 61 are so wound as to tend to turn the rods 0, so as to move the receivers together toward the callboX, and projections b upon the bearings limit the movement of the rod and receiversupporting bracket in the opposite direction.

The transmitter is provided with a fixed hook K upon one side and the usual movable hook K upon the other side, or when specially constructed for use with this apparatus a lever provided with a knob upon the on (1 therethe call-bell circuit in a well-known manner.

This is effected automatically by the following-described means: On the rod O, adjacent to the hook K, is secured an arm H, (see Figs. 6 and 7,) the end of which is inclined in such a way that when the springs (1 turn the rod C, as aforesaid, the arm H rides over and depresses the hook K to the same extent as if the receiver were hung thereon. hen the user of the call-box pushes aside the receivers, thereby breaking the call-bell circuit, and the receiving instrument being placed to the cars, they are adjusted vertically upon the rods 0 to suit the height and distance from the transmitter of the user, and are then held automatically by the springs d, operat ing to turn the rod C, until the arm H moves off from the hook K, the lever of which is adapted to either make or break the call-bell circuit as it opens and closes the main telephone-operating circuit. After the converfor holding said arm toward the user of the instrument, and an arm fastened to said vertical rod to swing across and press down said hook for closing the call-bell circuit when the instrument is not in use, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

PHILIPP J OHANN BOSE.
